The basic features of the computer, which contained five major reasons as follows: 1. work with the electronic systems (electronic machine). A computer is an electronic device to save the data. Processing and display the results. Storing data through the keyboard or other device. These data are converted into electrical signals for the computer to understand and can be processed, and when the computer was successfully processed. The information is converted back into electrical signals, in a format that can be understood by humans. 2. work with a high speed (speed). Because of the operation of a computer system is electronic, so the operation can be done so quickly (over a billion command in one second). 3. reliable accurate (accuracy and reliability). The computer will work on a human programming or instructed. If the user enters data and commands with accuracy. The result of processing, it will be accurate, reliable, 4. storage (storage) Computer memory that stores the data into The ability to store this information will depend on the size of the computer, such as a micro-computer backup storage unit that can save more than one million letters. 5. data link communication (communication) Computer to communicate with other computers, and can be a lot better than using a computer as a single system. For example, a computer connected to the Internet to retrieve information from a different computer (remote computer). From the properties of a computer, we can see that the computer can perform many tasks that humans can not be done, or if humans do, it takes a lot and have a lot of errors, such as the calculation of several major figures, as many within the time limits, work in the same way repeatedly millions or recognize the numbers and letters of several tens of thousands of pages, without forgetting. Tedious and cumbersome, we can use these computers work instead. We have only to order only.
